This is a convenience function for extracting a captured substring into a given buffer. The arguments are:
subjectSubject that has been successfully matchedovectorOffset vector thatpcre_exec()usedstringcountValue returned bypcre_exec()stringnumberNumber of the required substringbufferBuffer to receive the stringbuffersizeSize of buffer
The yield is the length of the string, PCRE_ERROR_NOMEMORY if the buffer was too small, or PCRE_ERROR_NOSUBSTRING if the string number is invalid.
There is a complete description of the PCRE native API in
the pcreapi page and a
description of the POSIX API in the pcreposix page.
